CARBURE'I'ER.

Application filed March 2, 1e17, Serial No. 151.983.

To all whom it may concern:

Be it known that I, AXEL EMIL EKLUND, a citizen of the United States, residing at Brooklyn, Kings county, and State of New York, have invented and discovered certain new and useful Improvements in Carbureters, of which the following is a specification;

My said invention relates to carbureters for internal combustion engines, and consists in the combination and arrangements of elements hereinafter described and particularly set forth in the accompanying claims.

The invention has for its purpose to provide a carburetor, whereby the heat from the exhaust gases of the engine may be utilized to vaporize fuel charges from ordinary liquid hydrocarbon, thereby imparting to the vaporizer the highest degree of efiiciency.

The invention has for its further purpose to economize space in mounting the carbureter on the engine, and to utilize the heat of the exhaust at its highest temperature; and one in which a constantly heated body initially receives the jets of gasolene and conditions the same for the further heating thereof, which occurs in its passage to the engine cylinder.

Another purpose of the invention is to construct a carbureter of few parts that may be readily assembled or disassembled, and

- having means for adjustment to vary the amount of gas produced in accordance with the demands of the engine.

The invention is disclosed by way of illustration in the accompanying drawings, wherein Figure 1 is a central vertical sectional view of the carbureter, and

2 a transverse sectional view thereof taken oii the line 2.-2 in Fig. 1.

Referring to the construction in further detail, and wherein like reference characters designate corresponding parts, the carbureter consistsnofacasing or reservoir 3, having a removable cover 4, and adapted to receive the liquid fuel from the source of supply (not shown) through the pipe inlet 5.

I A float 6, of any appropriate type, is lo cated within the vessel 3, and automatically operates to raise or lower the valve 7 that controls the flow of gasolene from the sup-- ply into said reservoir 3. The valve 7 is mounted on a stem or rod 8, working Specification of Letters Patent.

through a collar 9 on the cover plate 4, and is adapted to be moved-to seat or unseat said valve 7 by the pair of levers 10 that are fulcrumed on the studs ll secured to the closure plate l. The outer ends of said levers 10 contact with the upper surface of the float 6, and the inner ends of said levers engage with a collar 12, mounted on the valve stem 8, and by this arrangement, the raising and lowering of the float will seat or unseat the valve 7, as will be understood.

A tubular casing or cylinder 13 is located adjacent the gasolene tank 3 and provides the chamber within which the liquid fuel is vaporized prior to delivery into the engine cylinder; and said cylinder is constructed at one end with an aperturcd flange 14 for mounting on the motor, and at its other end 15 is closed. The closed end is provided with a plurality of apertures 16 adapted to register, in varying degrees, with similar openings 17 formed in a ring 18 that is adjust-ably mounted in the cylinder 13, as shown. A hand-gripping piece 19 is secured to the perforated ring 18 and serves for adjusting said ring to regulate the proportion of air to be mixed with the fuel charges.

A butterfly-valve 20 is pivotally mounted in the charge forming chamber at the outlet end thereof for regulating the volume of gaseous mixture to be delivered into the engine. The means for actuating said valve comprises an arm 21 secured to the valve shaft 22, and connected with the rod 23 that also connects with a suitable control.

A jacket 24 is mounted on, and surrounds a portion of the cylinder 13, and is adapted to receive the exhaust gases from the engine through the intake opening 25, and discharges said gases into the mutiier, or direct to the atmosphere, through the outlet opening 26. The heat from the exhaust gases within the jacket serves to form and initially heat the fuel charges that are delivered into the cylinder by the suction strokes of the piston. Said nozzle 27 communicates with the fuel reservoir 3 through the passage 28, as shown, and is detachably mounted on a tubular member 29 projecting from the inner wall of the cylinder 13.

It is proposed to have a constantly heated body to receive the jets of fuel issuing from 1 the nozzle 27 and initially disintegrate the same, and to this end a plug 30 projects through the-side wall of the cylinder 13-, and
